Chicago feds: Didn't use expanded surveillance

CHICAGO — Federal prosecutors have responded to a defense call for the government to reveal if an expanded U.S. surveillance program led to terrorism charges against a suburban Chicago teenager.

Adel Daoud is accused of trying to ignite what he thought was a car bomb near a downtown Chicago bar.

In a filing in U.S. District Court late Wednesday, the government denied a defense contention that prosecutors may have used a 2008 amendment expanding the scope of a foreign intelligent law to charge the 19-year-old Daoud. The government filing says investigators relied on pre-2008 provisions.

The Hillside teen, arrested in an FBI sting operation last year, has pleaded not guilty to terrorist charges. He remains jailed in Chicago awaiting trial, which is set for Feb. 3.
